Buggy code:
public class MainForm extends AppCompatActivity implements AsyncResponse { EditText txtRow ; EditText txtNumber ; EditText txtCode ; EditText etName ; EditText etMail ; EditText etMobile ; ListView boxListView ; ListView lvSend ; TextView tvRowCounter ; TextView tvCustomerCounter ; TextView tvBoxRequest ; ArrayList myStringArray = new ArrayList < String > ( ) ; ArrayList list2 = new ArrayList < String > ( ) ; ArrayList myBoxArray = new ArrayList < String > ( ) ; ArrayAdapter < String > arrayAdapter ; ArrayAdapter < String > arrayAdapter2 ; String cookieSelectedType = "1" ; String boxSize = "1" ; String REQUEST_NUMBER = "" ; String BOX_NUMBER = "" ; Boolean box = false ; int boxRequest = 0 ; ArrayList < String > list1 = new ArrayList < String > ( ) ; @ Override protected void onCreate ( Bundle savedInstanceState ) { } public void onClickRow ( View view ) { } public void onClickClear ( View view ) { } public void onClickRowComplete ( View view ) { } public boolean checkCodeValidation ( ) { } public void onClickEnter ( View view ) { } public void onClickDel ( View view ) { } protected ListView getListView ( ) { } protected void setListAdapter ( ListAdapter adapter ) { } @ Override protected void onDestroy ( ) { } public void boxRow ( int i ) { } public void onClickInsert ( View view ) { } @ Override public void processFinish ( String result ) { } public void onClickCOne ( View view ) { } public void onClickCTwo ( View view ) { } public void onClickCThree ( View view ) { } public void onClickCFour ( View view ) { } public void onClickCFive ( View view ) { } public void onClickNewCustomer ( View view ) { } public void onClickSizeOne ( View view ) { } public void onClickSizeTwo ( View view ) { } public void onClickSizeThree ( View view ) { } public void onClickSizeFour ( View view ) { } public void onClickSizeFive ( View view ) { } public void onClickSizeSix ( View view ) { } public void onClickRegisterCustomer ( View view ) { } public void onClickRefresh ( View view ) { } public void onClickPrint ( View view ) { } public void onClickCancel ( View view ) { } public void onClickTemp ( View view ) { } private class ReadDataSend extends AsyncTask < String , Void , Boolean > { ProgressDialog dialog = new ProgressDialog ( MainForm . this ) ; @ Override protected void onPreExecute ( ) { } String text = "" ; @ Override protected Boolean doInBackground ( String ... urls ) { } @ Override protected void onPostExecute ( Boolean result ) { if ( result == true ) { lvSend = ( ( ListView ) ( findViewById ( R . id . lvSend ) ) ) ; lvSend . setAdapter ( new ListAdapter2 ( MainForm . this , list1 ) ) ; try { lvSend . setOnItemClickListener ( new AdapterView . OnItemClickListener ( ) { @ Override public void onItemClick ( AdapterView < ? > parent , View view , int position , long id ) { HashMap postData = new HashMap ( ) ; postData . put ( "txtBoxNumber" , list1 . get ( ( ( position * 4 ) + 2 ) ) ) ; PostResponseAsyncTask task = new PostResponseAsyncTask ( MainForm . this , postData ) ; <START_BUG> task . execute ( "http:////gpspro.dx.am//store//edit//requestBox.php" ) ; <END_BUG> Intent i = new Intent ( MainForm . this , EditActivity . class ) ; startActivity ( i ) ; } } ) ; } catch ( Exception e ) { showMsg ( getString ( internetConnection ) ) ; } } else { showMsg ( getString ( internetConnection ) ) ; } dialog . dismiss ( ) ; } } void showMsg ( String msg ) { } }

Fix:
task . execute ( ( ( getString ( con ) ) + "store//edit//requestBox.php" ) ) ;
